Janet Jackson cancelled her world tour amid rumors she was battling throat cancer.

Janet Jackson may have throat cancer after a tumor was found in her throat. Jackson canceled her “Unbreakable” world tour in December 2015 to get surgery.

If Jackson does have a malignant cancerous tumor, it’s likely she will never sing again.

“God forbid that this should be cancer of the larynx,” said Dr. Stuart Fischer.

“That would abruptly end her ability to ever perform again. Singing would be impossible. Surgery would be very complex, followed by months of radiation treatment.”

Sources said doctors found a tumor on Janet’s vocal cords. “It’s a medical condition that has to be taken care of immediately,” an insider told Radar.

Janet kicked off her sold-out world tour in August 2015 to trumpet her new album, Unbreakable, which has received glowing reviews.

Janet Jackson has maintained her 60 pound weight loss for several years.

In the artwork for “Unbreakable,” Janet looked gorgeous and healthy following her recent 60-pound weight loss.

The 5-foot-4 Janet, who once topped the scales at over 180 pounds, shed the weight on a low glycemic index diet, which is based on managing blood sugar levels, as Celebrity Health Fitness has reported.

Jackson is a self-professed emotional overeater, who binged when she was unhappy, bored or anxious.

“I think people really connect with the idea of someone who has gained and lost weight in this very public way, and also someone who’s an emotional eater. Chocolate, cake, caramel apples—there aren’t many things I don’t love,” said Janet.

Janet Jackson said she gained weight due to emotional overeating.

Janet says she’s happy with her appearance and her improved health following her 60-pound weight loss. “I honestly don’t even know what size I am,” said Jackson. “Now it’s about looking in the mirror and saying, ‘I feel good. I feel healthy.’ ”
